Ioall whom, it may concern: Beit known tl at I, BERNARD H. LARKrN, a citizen of the .United States, residing in Ma'ywood, in the county of Cook and State oflllinois, have invented a new and useful 1m rovernent in Hinged gCovers forSquare or qtangunr sh a-na l Bans or Boxes,

The object of my invention is .to provide a ne recta gu n ed ov or-d s- P .ay l ans .01 box s of a p e, ro g, ci nt; and r miabl const uction whi h m y b heaply manu ac ured an i hou he their solder, thus giving-the cover a uniform an r at pp arance.and'ehablin it to be marine li d and pol e f om time to tit-peas mayb equired- 1 My invention consists in the novel conamnion tdevi es a d in o l combi- Perts a d ev ee h e n, sh a H by which this object or result .e' lyaes omplish d .1

a detail ertic l se io m ar t Fig 4i, s wing the parts before the same are cleric or upset. Fig. 6 is a horizontal sectionfe the cover, and Fig 7 is a detail vertieeetien o lin 7 of e- "In th d ings, A represents a sheet-metal Wi 01. box having three vertical (t preferably of n-P a nd a front provided w th 'd pl yp n t dosed by a removable as p a an a $2 an 1in it. c o ed y a removable sig11- plate, v '1" n e sheeternet'al box A maybe of tab e cons ruc ionl v the. s'heetemetal hinged; cover of the Mean-or box. The cover B has a Hat to portion 7) and; three integral right-angle anges ,or sides b." b 6 preferably of tin-plate, each furnished with a wire'roll b at its lower edge, embracin the wire C; which surrounds the g ven and whigh atthe back of. the cover eompanr n'g d awings, ch

forms the intle of its hinge and cooperates with the'hln'ge-straps D, secured to the back side of the can or box. I) at the back side of-the cover is provided The. integral flange with integral right-angle overlapping li s12,

preferably of substantially semiclrcular s ape, which fit in corresponding semicircular coun- .tersinks or recesses b in the integral adjacent flangesor sides I) b of the cover. The counterslnks orrecesses b cause the overlapping lips to fit substantially flush with the'sides b b of the cover. The front side 6 of the cover. is preferably of sheet-brass, corresponding to the brass front of the can or box,

and is secured to the cover B by a right-angle flan e or fold b enga ing a similar flange or fold on the cover .at the front edge thereof, theinterlocked folds being snu compressed together. I) b, uniting the cover B and its'brass front or side. 5 are further locked against disengage'rnent by a series of depressions, points,

or teats b ,,-forrned in the sameiby blunt punch; These Small. rounddepressio'ns If", in connection with the. loek seain' formed by the interlocl edpfolds, securely unite thebrass front side to the c'o'ver. W bjis further provided at its ends with. overlapping lips b identical to the lips b before described, which fit in semicircular countersinks or recesses b in the adjacent flanges or sides 11 b of the cover. semicircular lips I) on the back side I) and on the brass front side b are secured to the adjacent sides 12 b of the cover by integral eyelets or hollow burs b, which are punched through the adjacent sides b b of the cover;

burs 1), formed on the a jacent sides?) b and the two hollow burs b I)", being upset or clenched down upon each other, thus very Theinterlocked f0 ds The brass front side The overlapping firmly and securely unite the overlapping:

front and back sides I) b? with the adjacent sides I) 5 without solder and leave the overas are occasioned where solder is employed.

for uniting the of the cover.

The hollow burs b b are simultaneous? lips I) with the adjacent sides formed in the lips I) and adjacent eidesb 3 of the cover ,by simply forcing a blunt punch I sinks to receive said overlappinglips, substanthrough the two superimposed thicknesses of sheet metal, and then by a second operation the interen aged hollow burs b b are' upset, thus secure y unitin the parts.

As the four depending sides 1), b b and b of the cover are secured together at the corners by the overlapping right-angle lips b and countersinks b and interengaged and clenched hollow burs b 1)" without the use of solder, the cover may be rapidly and cheaply manufactured, While at the same time the cover ismade very strong and firm.

I claim 1. A square orrectangular sheet-metal display can or box, provided with a hinged cover, having a top portion and three integral sides, and a front side of separate metal secured to the top of the cover by interengaging folds or flanges and a series of lockin points or projections, said front sidean back side ofthe-cover having right-angle lips overlappin the adjacent sides of the cover and secured together by integral hollow burs 0r eyelets on said lips extending through the adjacent sides of the cover and upset or clenched down, substantially as specified.

2. A square or rectangular sheet-metal display can or box, provided with a" hinged cover, having a top portion and three integral sides, and a front side of separate metal secured to the top of the cover by interengaging folds or flanges anda serlies -of lockin points or projections, said front side and back side of the cover having right-angle lips overlappin the adjacent sides of the cover and secure together by int ral hollow burs or eyelets on said lips exter 'ng through the adjacent sides of the cov'elr, sidesf of the cover having rehesses or counter- .the corners coveringthe end side with said. ad acent tially as specified.

3. A display can or box cover having, three integral depending sides and a front side of la separate piece, interengaging folds or flan es uniting said separate front side with t e cover, said separate front side havin integral external overlapping right-angle lips at edges of the sides overlapped thereby, said integraloverlapping lips on said separate front side having integral hollow burs extending through the adjacent sides and upset or clenched to secure said separate'front side to the adjacent depending sides of the cover, and said adjacent integral sides of the cover having couptersinlks or reclesses to refieive said ri htan e over a in i s on sai se arate piece fro ht side, siib sta nti lly as specified 4. A sheet-metal cover for cans or boxes, having three integral depending sides and a front side of separate metal, interengaging folds or flan es uniting said separate-front vt 1e cover, said interengagiug flanges or folds having a series of locking points or depressions, substantially as specifled.
